(October 31, 1962)

This is a Circular Airgram from the Department of State to certain
posts concerning the visit by two U.S. scientists to the Israeli nuclear
reactor at Dimona.

Reftel (sent all addressees except Algiers) authorized addressees inform
governments to which accredited of results unpublicized visit in spring
1961 by two qualified scientists to Israel reactor site at Dimona. According
to observations then reported, Dimona project appeared of type and magnitude
described publicly by Israel leaders (e.g., research reactor with 24 megawatt
capacity). While they also concluded reactor upon completion in two or
three years would produce small quantities plutonium as do others of comparable
size and character, our experts found no evidence Israelis preparing produce
weapons. We noted, accordingly, that observations US scientists tended
support public and private assurances re peaceful intent Dimona project.
We further noted that highest levels this government opposed to proliferation
nuclear weapons production capabilities and had so informed Israel.

Recently there has been further visit by American scientists to Dimona
reactor. This enables us renew statements of June 1961 that latest observations
again confirm Israeli statements that reactor intended for peaceful
purposes only. There no evidence of preparation for nuclear weapons
production. Work on reactor progressing normally.

Unless strong objection perceived, action addressees should orally
convey information preceding paragraph promptly and in confidence to
host governments at level deemed appropriate, although we would wish
be assured information will become known at highest levels. Missions
should report action taken and reactions noted.

For Damascus: Since no approach was made in Damascus last year, your
statement should be altered appropriately.

Info addressees, with exception Tel Aviv, may use foregoing in discussions
with local government as seems desirable and useful do so. We discussed
with Canadian and UK Embassies October 23. Cairo instructed separately
re approach UAR.

Department intends initiate no publicity with regard visits by scientists.
If leaks occur, US spokesman will say two US scientists recently in
Israel in connection with US Atoms-for-Peace Agreement had opportunity
visit Dimona installation which they observed to be of nature and scope
publicly disclosed by Israel Government. Suggest addressees take similar
line in response responsible press inquiries.
